Singer Kwon Eun-bi recently gave fans a glimpse into the dedicated routine behind her fitness transformation. Taking to social media with the simple caption "April," Kwon Eun-bi posted several photos showcasing her clearly defined abdominal muscles while wearing a sports bra and leggings. A featured video also highlights her disciplined approach, showing her performing a core workout on a mat with steady, controlled form.
The Twist Plank: Targeting Abs and Obliques Simultaneously
The core exercise demonstrated by Kwon Eun-bi is the "twist plank," a variation that introduces pelvic rotation to the traditional plank. This movement is highly effective because it engages the primary abdominal muscles alongside the obliques and spinal stabilizer muscles.
To perform the move, start in a standard plank position with your elbows directly under your shoulders and your body in a straight line. Slowly rotate your pelvis to one side, lowering it toward the floor, before returning to the center and repeating on the opposite side. The key to effectiveness is keeping the upper body as still as possible, ensuring the movement is isolated to the pelvis.
Proper Alignment Over Momentum
Precision is more important than speed when it comes to the twist plank. Using momentum or dropping the pelvis too low can decrease abdominal engagement and place unnecessary strain on the lower back. It is vital to maintain proper body alignment—ensuring the lower back does not sag and the shoulders do not round—while keeping your gaze naturally directed toward the floor.
Beginners should focus on form rather than volume, starting with 8 to 10 repetitions per side. As strength improves, a standard goal is 10 to 15 reps per side for three sets. Alternatively, a time-based approach of three 30-to-60-second sets can be equally effective. To maximize recovery and performance, rest for 30 seconds to one minute between sets.
